Babylon 5, an eight-kilometer space station, two and a half million tons of metal, inhabited by earthlings and aliens who came from five different solar systems. The purpose of the station is to coexist in peace. Ambassador G'Kar from the Third Circle of the Narn regime is dead! A faithful friend of the crew of the Babylon 5 space station died as a result of the explosion of his shuttle. The first officer of the station, Susan Ivanova, as well as the head of the station's security service, Michael Garibyldi, are ready to do anything to find out the cause of the ambassador's death. But a message received by G'Kar a few hours before the tragedy makes them doubt that this is an accident: “I swear with blood to devote my entire life to revenge, as our laws allow me.” Ivanova and Garibaldi do not even suspect that their investigation will lead them straight to the heart of Narn society. Alone in this strange and often dangerous world of castes, customs and conspiracies, unable to trust anyone, Ivanova and Garibaldi, in turn, become targets themselves. From Babylon 5 to Narn, danger is everywhere. But where is the killer... if there is one?
